Introduction

SOFA and SAPS II scoring is used for monitoring of organ function and outcome prediction in intensive care. We evaluated the use of these scores to analysis the different subgroups of patients admitted to our ICU.

Methods

Over a period of nine months (between October 1998 and June 1999), the first five days scores of SOFA and SAPS II, were prospectively calculated for all consecutive patients (length of ICU stay >12 h) admitted to our 10-bed medical-surgical ICU. We stratified patients using three different subgroups: 1) medical (M); 2) surgical, elective (E); 3) surgical, unscheduled (U). Organ failure if SOFA score ≥ 3. Mortality was assessed at ICU discharge. Data analysis and statistics were performed using the Statistical Package for Social Sciences (SPSS) version 6.0.1 for Windows.

Conclusion

We have in our ICU two subgroups of patients: 1) medical (M) and unscheduled surgery (E) with higher length of stay, higher scores, and higher mortality rate, compared with the second group-elective surgery(E). This is especially important when we try to compare the performance of different ICUs.
